HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 938, 394 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 938, 394 is 2 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 938, 394 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 938, 394 is 2.

HCF(938, 394) = 2

Highest common factor (HCF) of 938, 394 is 2.

Highest Common Factor of 938,394 using Euclid's algorithm

Highest Common Factor of 938,394 is 2

Step 1: Since 938 > 394, we apply the division lemma to 938 and 394, to get

938 = 394 x 2 + 150

Step 2: Since the reminder 394 ≠ 0, we apply division lemma to 150 and 394, to get

394 = 150 x 2 + 94

Step 3: We consider the new divisor 150 and the new remainder 94, and apply the division lemma to get

150 = 94 x 1 + 56

We consider the new divisor 94 and the new remainder 56,and apply the division lemma to get

94 = 56 x 1 + 38

We consider the new divisor 56 and the new remainder 38,and apply the division lemma to get

56 = 38 x 1 + 18

We consider the new divisor 38 and the new remainder 18,and apply the division lemma to get

38 = 18 x 2 + 2

We consider the new divisor 18 and the new remainder 2,and apply the division lemma to get

18 = 2 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 938 and 394 is 2

Notice that 2 = HCF(18,2) = HCF(38,18) = HCF(56,38) = HCF(94,56) = HCF(150,94) = HCF(394,150) = HCF(938,394) .
